hw/arm/stellaris: use qemu_find_nic_info()

Rather than just using qemu_configure_nic_device(), populate the MAC
address in the system-registers device by peeking at the NICInfo before
it's assigned to the device.

Generate the MAC address early, if there is no matching -nic option.
Otherwise the MAC address wouldn't be generated until net_client_init1()
runs.
